' To all whomjt may concern:

- 7 Be it known thatL DANmL'B -uoss, a citizen of the- UhitedIState's, and a resident oi'thefborough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful following is a specification..

Improvementsin Type-'Writing Machinesmf which the I I I I operative position where-it will cooperate with the types; I

A further objectiof the invention is to provide means for automatically feedinglthe' inking surfaces during the operation of the machine so asto efficiently use every portion of an inking surface and so nevertheless thatthe particular inking surface which has been moved to the operative position will. alone'be brought: into use. Y

To the above and otherendswhich will hereinafter appear my, invention consists of the features of con struction, arrangements of parts and combinations of devices to be hereinafter described and claimed;

In the drawings illustrating these improvements, Figure 1 represents the upper part of the left-hand end 1 of a type-writing machine with of the frame broken away to more clearly illustrate my invention. I Fig. '2 is a plan view of the'l ett-hand spool of the typewriting machine, showing the shifting frame, the supporting links, the shiftinglever and cam, one of the colored sections of the ribbon having reachedits limits in the lateral movement'in one direction. Fig. 3 is a similar view but showing the same colored section occupying the opposite limit of its lateral movement. Fig. '4 is a similar view but showing the other colored section at' the printing center or line and at its extreme limit in the lateral movement in one direction. Fig. '5 is a view similar to Fig. 4 but showing the same colored section of the ribbon at its opposite limit in the lateral movement.

Fig. 6 is a vertical section through'the hubs of one of the and showing the mechanism arranged for automatically producing the lateral feed within one color or section Remington machine, though it should be understood that it may be applied to other characters of writing machines. i

' thatclass which has a carriage 1 in which is mounted a piaten 2, the carriage being arranged to: travel along the top plate 3 from side to side of the machine and being agency of a strap or bands and a springhwithin the drum. The carriage driving drum 4 revolves freely on v a supporting shaft 5" and is provided'on its front side with a pawl 6 which .en'gagesthe teeth of a ratchet wheel men t otthecarriage 1,- in'the'direction of its feed'or turned to its starting point,- the drum' revolves in the fratchet wheel 7', leaves it at rest. .The automatic actuation oi the ribbon mechanism being' effected from the ratchet wheel 7, itwillbe unddrstood thatdmingithe returnmovement oi the carriagefrom left toi'ight no able in order to affordimpact'oi the types throughout every portion of the ribbon with a consequent producwheel 7 carries on its hub a bevel gear and" a spider 9. The object of the latter will be described hereafter, but

gear 10 mounted on the shaft 11, tlie object of this shaft '11 in this class of typewritingmachines being wellknown as the means by which the ribbon spools are alternately wound to ehangethe direction of longitudinal fully illustrate this feature of the construction, it being understood, that the direction of longitudinal feed oi the ribbon depends on which bevel gear on the sh aft 11 and this is determined by the longitudinal disposition automatiereversing mechanism employed in the No. 6 Remington inachine and which is disclosed in the patent to WebbNo. 599,428 dated February 22, 1898.

In Fig. 9 the bevel gear wheel 10 will be seen attached nected thereto by a set screw 12. The sleeve 12 loosely surrounds the shaft 11, and has a crank arm 13 projecting therefrom and from which extends a pin 14, the pin extending paralled with the shaft 11 and passing loosely through a slotor opening in the end of a crank arm 15 secured to the shaft 11. This construction per mits of the longitudinal movement of the shaft 11, whether effected automatically or by hand, independently of the sleeves 12 and 12, the bevel gear 10, and

the crank arm 13, which parts are held against longituiio'in right to; left, the revolving drum and its pawl 6 I fturn theratchet'wheel 7, but when'th'e carriage is reto a sleeve 12, that receives a sleeve .12 which is coni The typewriting' machine shown in the drawings is 'of so propelled by the carriage driving drum 4 through the l 7 also looselymounted onlthe shaft 5 ,1 With themove A 5 oppositedirection and the pawl 6 iailing to act upon the 7 5 movement is transmitted-to the ribbon, which is desirtion of uniforin impressions in the writing; The ratchet it-will be seen that the gear 8 engagesa similar bevel feed of the ribbon. I do not think it necessary to more meshes with its associated gear on a ribbon spool shaft of the shaft and that these devices constitute parts of the The shaft 11 extendsfrom side to side of the machine and is provided at the left-hand end portion thereof with a bevel gear wheel 17 secured thereto and meshing with a similar wheel 18 on the shaft 19, which latte *shaft carries the ribbon spool and is in turn carried in brackets 21, 21. It will be understood that another like gear is carried near the opposite end of the shaft for cooperation with the gear of the other ribbon spool shaft 19 (Fig. 10);

The spider 9 is provided with several lugs 22, 22, which project outwardly, and as the ratchet wheel 7 and thespider 9 revolve, they strike the outer end of a lever 23 fulcrumed on the shaft of a ratchet wheel 24 carried by a bracket 25 hanging from the lower side of the top plate 3. V The lever 23 carries a pawl 26 which engages the teeth of ratchet wheel 24 and asthe lugs 22, 22 strike the outer end of the lever, cause it to rise and fall, the pawl playing in the teeth of the ratchet wheel 24 and causing it to slowly revolve and turn its shaft 27' and'a worfn 28 thereon. v The worm 28 engages a worm wheel 29 on a vertical shaft 30 carried by the bracket 25, and the shaft 30 at its other end carries a cam 31 which has about half its face stepped while the balance is a regular and steady rise. The spools 20 and 20 slide freely on the'shafts 19 and 19 but each spool is caused to revolve with its shaft by means of a spline on the shaft or any well-known or desired means which I have not considered necessary'to show, and the'ribbon A passes from the left hand ribbon spool, up and over a guide pin 32 and then over the type well to the other ribbon spool.

The guide pin 32 is carried by two ears 33 of a frame 34,

and the latter has depending from its lower side two fingers 35,'which span the associated spool and control its movement along the shaft 19. The frame 34 is carrie'd by two supporting links 36, 37 which are pivoted on vertical posts 38, 38 secured to the underside of the top plate 3.. These links 36 and 37 are provided at their pivotal ends with sleeves surrounding the posts .38, 38 which afford an easy swinging movement while their outer ends are pivoted to different sides of the shifting frame 34 and allow it to move fore and aft of the machine duringthe swing movement of the links. This movement is imparted to the links and shifting fame 34 by means of the small rocking lever 39 having a forked end 40 which carries a roller 41 designed to ride over the face of cam 31. The other end of the lever 39 is .pivoted on the post 38, which also carries the supporting link'36 and by means of the lever 42 is locked with the link 36 and moves with it about the pivot post 38.

The locking lever 42 is clearly shown in Fig. 6, where it will be seen fulcrumed in two ears 43, projecting from the sleeve of lever 39, its upper end bearing against and beingforcedout by a spiral spring 44 seated in a socket in that end of thesleevewhile the lower end of the lever 42 engages lugs "45, projecting from the sleeve of the supporting link 36. Fig. 8 shows three of these lugs and the longer end of the lever42 is designed to lie on'either side of the 'middle lug"and in the space between the 'middle and one of the end lugs, so that the lever and the I link may be positively locked with relation to each other in either of the two positions shown in Figs. 2 and 4. The spring 46 is wound about the pivot post 38 above the sleeve of supporting link 37 and one of its ends bears against the depending rim of top plate3.

The other end bearingagainst link 37 tends to force it and the shifting frame 34 with link 36 andlever 39 in the opposite direction and cause the roller 41 to ride on the face of cam 31. 'The top plate supports a ribbon guide plate 50 of the usual or any suitable construction. The inking surfaces comprising the ribbon A are shown as two fields 47 and'48, These fields be inking surfaces of two different colors such for instance as black andred, or they may. have different characteristics; thus the field 47 may be copying ribbon,- whereas the field or section 48 may be record ribbon, though for convenience the sections will be referred toasof two dif* ferent colors black and red. In Figs. 2 and 3, the'typ'es 49 act upon the black field or section of the ribbon while Figs. 4 and 5 show the red section in-use.

' The operation of the mechanism above described will 7 through theletter space movement of the carriage in the direction of the feed causes the lugs 22 of the spider 9 to strike the free end of the lever 23-a'nd the pawl 26 thus intermittently actuated turns the wheel 24 and worm 28. The worm wheel 29 is turned by the rotation of the worm 28 carrying with it the cam 31 whose cam face causes the lever 39 and link 36 to swingabont the post 38, moving the frame 34 laterally andphifting the spool 20 on the revolving shaft 19. The frame 34, through the ribbon guide plate 50,also shifts the ribbon spool 20 at'the other end of the machine by the usual depending finger 50 carried by the plate 50 (see Fig.- 10). The extreme movements of the black ribbon are shown in Figs. 2 and 3; in Fig. 2 the roller 41 rests on the shortest radius of the cam 31 and the types 49 areusing one side of the ribbon and in Fig. 3 .the cam has revolved and the roller 41 bears onthe greatest-radius, having gradually shifted thjs ribbon across the printing center and to its limit in the other direction. This shifting is slow and intermittent during the longitudinal .ufeed of i now be explained: The revolutions of the ratchet wheel the ribbon and eventually the entire colored sed tion of the ribbon both widthwlse and lengthwise considered is presented to the action of the types. The change of the colored sections of the ribbon from black to red is as follows: I v

The relation of the lever 39 and the link 36 are seen to differ in Figs. 2 and 4, and this is brought about by shifting the locking lever from the space 51 (Fig. 8) to the space 52 between the lugs 45, 45. This is' done by lifting 3 lever 42 out of the space 51 against the pressure of spring 44, shifting the link slightly to the right and dropping the end of the lever 42 into the space 52: as seen in Fig. 4. The'relationof the lever 39 and its roller with the cam 31 is the same but the link 36 has carried the shifting frame and the black section of the ribbon past the printing center and placed thered section in the position to be used. The actionof the cam 31, lever 39 and link 36 is now identical with that of have shown as beingequally divided in its'coloring through its entire length and but two colors being used. It is readily seen, arrangement of the lugs 45, on the sleeve of link 36, threeor more colors or sections may be used.

It will be observed that the lengthwise motion of the ribbon in either direction is in no way interfered with and the change of color or character of,.the printing surface is readily effected without touching the ribbon.

While a single ribbon or inking surface is here shown "and described, it is obvious, thatI may employ two or more ribbons or other inking surfaces, each of a single but different color or-c haracter.

.From the foregoing description. it will be observed that I have provided simple and eificient means for afiording an automatic feed of the ribbon or inking surface-in two directionsat substantially right angles to each other an'dthat the feed is nevertheless such that only the field which is in the operative position will be presented to the types for coiiperation therewith; that the link 36, lever 39 and the connections between the two constitute essentially abell crank lever, the separate arms(36 and 39) of which are adapted to be ad justed relatively one to the other to bring an inking field of one or another characteristic into operative position and to afford an automatic movement of the ribbon or inking surface so as to present onlythe field in the operadificrent characteristicefribbbn spools tive position to the action of the types; that the guide plate and the associated parts constitute a ribbon carrier which is operatively connected 'to and is actuated by the means for automatically moving the ribbon in a direction transverse to its length.

Various changes may be made without departing from thespirit of my invention and certainjf eatures may be employed without the others.
